Tire pressure is an important consideration. I have a theory that says that
the tire pressure should be slightly less than the pressure that it takes to
deform the surface the tire is rolling over since it takes more energy to
deform most surfaces than to deform the tire.
Some think that by
It's been going for a long, long time. To mention just a few:
Too many people die due to not wearing seatbelt = seatbelt laws.
Ford Explorers roll over because of low tire pressure = mandated TPMS
sensors in ALL car tires.
Insurance companies paying out because so many cars are stollen = $$$ key
